Title: Tape control system
Inventor: CAMPBELL RICHARD HOOD JUNIOR
IPC: G05B19/37
Filed: 1970-03-03
Abstract: 1,268,013. Programmed control of machine tools. PNEUMO DYNAMICS CORP. March 3, 1970 [April 8, 1969], No. 10048/70. Heading G3N. An automatic control system for machine tools is responsive to control information derived from a tape 36 by a photo-cell reader 42. Information from each row of the tape is applied, in parallel, to an amplifier 44 for signal discrimination and shaping. The amplifier output is fed to a shift register 48 and movement of the tape in the reader continues until a whole block is read and stored in the register. The position information is applied to digital-to-analog converters 54-56 for the slides of the controlled machine tool and spindle speeds to buffer registers 57-59, the outputs of which are applied to logic 61 controlling clutches. The programmed time interval between tape blocks is stored in a buffer register 62 which controls a counter 88, receiving squared pulses derived from a 60 Hz mains supply. The programmed output from the counter is fed to a divide-by-12 circuit 90 providing the timing signals for the system and a reader start signal through an AND gate 91 which can be gated for manual interrupt or recyling through a control 96 and a tape cycle unit 98. For each slide the output of the corresponding digital-to-analog converter is compared in a differential amplifier 70 with an instantaneous desired position of the slide on a line 71. The difference output is sampled and held in a circuit 68 in dependence on a timing signal on line 92. The held signal is then, through a variable attentuator 74, fed to an integrator 75 providing a 'should move' signal to a conventional position servo comprising differential and power amplifiers 81, 82, a servo valve 79 controlling hydraulic positioning cylinder 78 with feedback from a transducer 80. Facilities are provided for parity block and mode checking.

Title: Novel dibenzoheptaenes and salts thereof and a process for the manufacture of same
IPC: C07C63/72
Filed: 1959-03-24
Abstract: The invention comprises 5-hydroxy-5-aminoalkyl-dibenzo-cyclohepta di (and tri) enes and their acid addition and quaternary salts having a nucleus of the formula:  <FORM:0858186/IV(b)/1> wherein the broken line denotes an optional double bond, the 5-aminoalkyl group being an alkyl group of more than 2 carbon atoms, e.g. propyl, bearing one or more di-substituted amino groups (for example a dialkylamino group or a heterocyclic amino group in which the two alkyl groups are joined directly or through a hetero-atom to form a 5-or 6-membered ring such as a piperidine, morpholine or thiamorpholine ring) and optionally containing one or more alkyl, alkoxy and/or halogeno substituents on the dibenzoheptaene ring.  The compounds are prepared by condensing a dibenzocycloheptadi (or tri) enone-(5) with a saturated aminoalkyl organo-metallic compound, hydrolysing the condensation product and if desired converting from a salt to a free base or from a free base to an acid addition or quaternary salt.  The organo-metallic compound may suitably be a magnesium-, lithium- or zinc-organic compound.  The compounds are used pharmaceutically, suitably in the form of salts such as hydrohalides, sulphates, phosphates, acetates, tartrates, maleates, citrates, lactates, oxalates or ethanesulphonates or quaternary salts derived from alkyl or aralkyl halides or dialkyl sulphates.  Preferred products include the 5-dimethylaminopropyl, 5-piperidinopropyl and 3-chloro-5-dimethylaminopropyl-, 5-hydroxy-dibenzocyclo - heptadienes and 5-hydroxy-5-dimethylaminopropyl-dibenzocycloheptatriene. Dibenzocycloheptadienones used as starting materials are prepared by reducing the corresponding benzal-phthalides to give a dibenzylorthocarboxylic acid, e.g. 4-chlorodibenzyl-(21)-carboxylic acid, which is then cyclized to the desired heptadienone, e.g. 3-chloro-dibenzocyclo-heptadienone.  The corresponding trienones are made by brominating the dibenzocycloheptadienones and splitting off hydrogen bromide.  4-Chloro-benzalphthalide is made by heating phthalic anhydride with 4-chlorophenyl-acetic acid and sodium acetate. Specifications 858,187 and 858,188 are referred to.

Title: Improvements relating to automatically reclosing electric circuit interrupters
IPC: H02H3/06
Filed: 1923-04-16
Abstract: 196,606. Metropolitan-Vickers Electrical Co., Ltd., (Assignees of Reagan, M. E.). April 18, 1922, [Convention date]. Cut-out arrangements for automatically-reclosing sectionalizing circuit-breakers, of the kind in which the reclosing voltage is taken from the midpoint of a resistance which bridges the sections when the circuit-breaker opens,- comprise an overload switch in the circuit of the maintaining and' closing coil of the circuit-breaker normally biassed to the closed position and latched in the open position on overload or short-circuit until released by a voltage relay connected to the mid-point of the resistance. As shown in the Figure, the sectionalizing circuit-breaker 4 is closed and maintained closed by a winding 6 energized from the mid-point of the resistances 15, 16 through the contacts 9 of an overload relay 5. With excessive current in one of the sections 1, 2 the relay is operated by the series winding 10 to open the maintaining circuit and retain it open by means of the latch 12, whereupon the circuit-breaker opens, and closes back contacts 7, 8. The back contacts complete the operating circuit of an adjustable time relay 18 which, after a certain time, closes its contacts 20, thereby completing the circuit, to the mid-point of the resistance, of the voltage relay 22. When the voltage on the faulty or overloaded circuit is restored approximately to normal, the voltage relay closes, trips the latch of the overload relay and completes the closing circuit-breaker.
Patent GB-103125-A (GB)
IPC: F41A19/21
Abstract: 103,125. Solms, W. 1., (Assignee of Luciani, J.). Dec. 30, 1915, [Convention date]. Machine guns. - Relates to hand-operated multi-barrel machine guns, and consists (1) in releasing the firing-pins corresponding to the various barrels successively in such a way that only single rounds or a small number of rounds are fired at a time, this being effected by a series of cams which are so set with respect to one another that the intervals between the firing of each round or group of rounds are not less than the time taken for a bullet to leave the barrel, and (2) in providing special locking-means for the breechblock. The invention is shown in Fig. 1 applied to a machine gun of the kind described in Specification 13404/15, in which a breech-block 3 is moved rearwardly by operating a lever 23 to allow a cartridge-loading plate to fall by gravity into loading position and to cause rods 2 connected to the firing pins 1 to pass between jaws 5. When the lever 23 is returned, the cartridges are loaded into the breech chambers, and the firing-pins are held by the jaws and thereby cocked. The jaws are subsequently opened to fire the gun, by operating a lever 12 which rotates a cam shaft 7. According to the present invention, cam shafts 6, 7, 8, geared together, are provided one for each tier of barrels, and the cams thereon are arranged as shown in Fig. 6, so that the tiers of barrels are discharged in the order a, b, c, the barrels in each tier being discharged in the order singly or in pairs as shown by the roman numerals in Fig. 7. The rods 2 are slidably mounted in the firing-pins so as to reduce the space at the rear of the barrels. The breech-block is locked in the firing position by a sliding block 26 having inclined interrupted locking-projections engaging corresponding recesses in the cradle 29. The rearward movement of the lever 23 first lowers the locking-block through levers 21, 16, and afterwards, by the engagement of a roller 20 with a slot 25, moves the breech-block rearwards. The locking-block is again raised to locking position at the end of the forward movement of the breech-block. Fig. 8 shows a modified form of locking-block 32 for use when the breech-block is operated by links 39, 36. The locking-block is moved into locking position by a projection 41 on the lever 39 and is moved out of locking position by springs 35.

Title: Valves for fluid tanker vehicles
Inventor: COCKLE EDWARD PETER
IPC: F16K27/07
Filed: 1964-03-11
Abstract: 990,509. Valves. TORRIDON STEEL Ltd. March 11, 1964, No. 10333/64. Heading F2V. In a tank vehicle 10 having a disc-type valve 15 (Fig. 2), arranged to control the flow of liquid from the base of the tanker compartment 11 through an outlet 13, the operating mechanism for the valve comprises a rod extending from the valve upwards through the upper wall 30 of the compartment, control mechanism 27 arranged to act on the upper end of the rod so as to lift it, and hence the valve, when desired, the control mechanism including a manual control member 32 and being such as to enable the rod to rise without movement of said manual control, and further control mechanism comprising an hydraulic piston and cylinder assembly 40 arranged to act on the lower end of the rod, which projects through the outlet passage 13, and a master hydraulic piston and cylinder assembly (Fig. 3), which delivers hydraulic liquid under pressure to the piston and cylinder assembly 40 to lift the rod and open the valve and arranged to be actuated by a manually-operated lever 63 capable of being retained against unintentional movement from the position in which it maintains the valve open. The mechanism 27 includes an inner cam element 33 which can slide vertically but is held from rotation by two splines on a sleeve 28 fixed to the roof of the tanker. A movable dome 31 with a handle 32 acts through a pin and bushing 34 moving in a slot 35 in the sleeve 28 on the cam surface 36 to raise and lower the rod and so open and close the valve. A spring 38 urges the cam downwards on to the pin, but a force upwards on the valve through rod 46 from the other operating mechanism allows the valve to open and the rod and cam to move upwards against the action of the spring. In the master cylinder, Fig. 3, an inlet 51 is connected to a pressure fluid reservoir, and an outlet 52 connects the apparatus to the piston 40. A piston 55 is connected by a spring 57 and a rod 59 to a member 60 housing a valve 61, this valve permitting replacement of fluid loss through leakage in the system when the piston is in the position shown. The piston is operated by a lever 63 acting through a roller 65 on the cam surface 66 of a member 67 which slides between plates 70 and a member 68 to move the piston, pin 72 guiding the member 67 and pin 73 connecting the same to the rod 75. When the lever is moved fully downwards the roller passes a " dead-centre " position on the cam surface, and the lever is thus held in the downward position. Each compartment of the tanker has its own operating mechanism, and the operating levers are all on the same axis, but may be grouped at any convenient position on the tank vehicle.

Abstract: 492,252. Lathe &c. bar feeds. HERBERT, Ltd., A., and HEARD, F. G. April 5, 1938, No. 10365. [Class 83 (iii)] Stock-feed mechanism for a lathe &c., comprises a tubular member, Fig. 2, formed of hinged parts 11, 12 in which the stock and a pusher 16 therefor are carried, and which can be opened to allow of loading the stock. The hinged parts may be of wood to reduce noise and a groove 19 is provided along the side of the lower member in which a bent portion of the pusher engages to prevent the latter being displaced when the stock is being inserted. The pusher is connected by means of a flexible cord 24, Fig. 1, to a weight 23 passing over a pulley carried by a bracket on the outboard support 20 for the stock tube. The flexible cord terminates with a shackle 28, Fig. 2, the pin of which passes through a slot 29 in a lever 26 connected by a hinge pin 27 to the stock pusher. The shackle is shown in its normal position for feeding the stock but when moved to the other end of the slot in the lever 26 a projection 31 on the latter is pressed against the stock tube and movement of the pusher is thus prevented. Alternatively, the flexible cord could be given a twist around a pin on the lever arranged at the position of the slot-end 30 to produce the same effect.

Abstract: 1,140,863. Digital calculators. AUTOMATIC TELEPHONE & ELECTRIC CO. Ltd. 17 May, 1966 [11 March, 1965], No. 10471/65. Heading G4A. A multi-purpose synchronously-controlled shift register comprising one or more similar register units (modules) connected in series, each unit being capable of receiving and delivering binary data in serial or parallel form, further comprises a two-state device for each unit being effectively connected differently to the unit according to the purpose for which the unit is employed, the two-state device selectively acting (a) as a plus one or minus one injection device when a plus one or minus one operation is to be effected on the unit contents, (b) to provide the result or carry digits when the contents of two units are to be added or subtracted, (c) as a digit repeating device in an addition or subtraction operation for reinserting the contents of one operand register unit into the latter in step with the insertion into the other operand register unit of the result of the operation. Each register unit comprises three subsections, each of four toggles interconnected through gating. Processing is by serial read out from each of the register units involved via gating to their respective two-state devices, called " processor toggles," and from there via gating back to the registers, the operand or one of the operands being modified in the process. In the add-one operation, which can be used to increment a microprogramme address, the state of the processor toggle indicates during the operation whether any of the operand bits yet to be shifted from the register require modification or merely reinsertion unmodified. Strobe pulses used by the system come from a delay line adjustable taps on which feed strobe repeater toggles, one per register unit, through AND gates which enable particular register units to be selected. The arrangement permits different register units to be synchronized.
